45.50 is 30% of what number
m_a_m_a [10]

Answer:

31.85

Step-by-step explanation:

to subtract 30 percent from 45.50 just divide the percentage (30) by 100 subtract this value form 1 then multiply it by the initial value (45.50) so

final value = 45.50 x ( 1 - \frac{30}{100} )

final value = 45.50 x ( 1 - 0.3)

final value = 45.50 x (0.7)

final value = 31.85  

subtract 30% is the same as discount 30% this operation could be for example a 30% discount on 45.50

note: 0.3 can be found just by moving the decimal point 2 places to the left \frac{30}{100} = 0.3 as a decimal

Solve<br> 6x−10(x+12)=−4x−24<br> Show your work.
gladu [14]

6x - 10(x + 12) = -4x - 24

<em><u>Distributive property.</u></em>

6x - 10x - 120 = -4x - 24

<em><u>Add 10x to both sides.</u></em>

6x - 120 = 6x - 24

<em><u>Cancel like terms.</u></em>

<em>Add 24 to both sides.</em>

-96 ≠ 0.

This equation is incorrect, as -96 will never be equal to 0.
